ROY F. BOYD, OF VENICE, ILLINOIS.

NON-REFILLABLE BOTTLE.

To all whom it may concern:

Be it known that I, ROY F. BOYD, a citizen of the United States,residing at Venice, in the county of Madison, State of Illinois, haveinvented certain new and useful Improvements in Non-Refillable Bottles;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to non-refillable bottles.

The object of this invention is to improve the construction ofnon-refillable bottles in such a manner that a practical valve mechanismwill be provided which, while permitting the liquid to be poured fromthe bottle will be properly constructed to prevent the bottle from beingrefilled, even by the wellknown tricks with which so-callednon-refillable bottles have been heretofore fraudulently manipulated inorder to fill the bottles in spite of the valve mechanisms with whichthey have been provided.

With the above objects in view and such others as may hereinafterappear, my invention will now be fully set forth and described,reference being had to the accompanying drawing:

In the drawings Figure 1 isa vertical section through the non-refillablemechanism,

Fig. 2 is a side elevation of a stopper device.

Fig. 3 is a section on line 3-3 of Fig. 1,

Fig. 4: is a section on line H of Fig. 1, and

Fig. 5 is a vertical section taken on line 5-5 of Fig. 1.

Referring more particularly to the drawings, 1 represents a bottlestructure which has a straight cylindrical neck 2. Preferably adjacentthat point where the neck 2 of the bottle 1, the neck is internallyprovided with an annular offset 3 which forms an inclined or conicalseat 4. The seat 4 receives an inverted conical valve or plug 5 of glassor other magnetically non-conductive material, said valve 5 at its baseor upper end being just sufficiently smaller than the internal diameterof the neck to permit it to unseat when the bottle is inverted. At asuitable intermediate distance betvween the seat 4 and the mouth of theneck, the latter is internally Specification of Letters Patent.

provided with the opposite notches or recesses 6, which are adapted tobe engaged by suitable locking devices as will later ap pear. Fittedwithin the neck, and extend ing almost to the valve 5, is a stopper 7which I prefer to make a clear glass, the stopper 7 having its lowerface slightly rounded in opposition to the convex upper face of thevalve 5, so that when the valve and stopper come into contact, aslightrocking action may occur therebetween. Passing diametrically through thestopper 7 is a tubular opening 8 which terminates at its extremitiesinto lock notches 10 which are adapted to cooperate or coincide with thelock notches 6 in the neck of the bottle when the stopper is seatedtherein, the notches 1.0 and 6 together providing recesses for thereception of the keys 11 which, when the stopper is seated in position,are held in locking posit1on,by means'of the coil spring 12 whichprojects through the passage 8. Obviously, the notches 10 must be ofsufficient depth to contain the keys 11 until the notches 10 have comeinto full coincidence with the notches 6.

In order to permit the passage of liquid from the bottle, the stopper 7is provided with the zig-zag or tortuous ports 13 which are preferablytwo in number, and are distorted in opposite directions, and furthermorelie upon opposite sides of the passage 8. By the provision of the twoports 13,

liquid may be poured from'one, while air isadmitted to the bottlethrough the other. In order to properly protect the contents of thebottle against leakage and other loss until sold, the plugs 14 areinserted in the upper ends of the ports 13 and are therein sealed bymeans of wax or any other suitable material which will not prevent theirready removal.

The assemblage of my improved bottle structure is apparent from theforegoing description. In its operation, the plugs 14% are first removedand the bottle then inverted in a position to permit air to enter oneport 13 while the contents may pass out of the other. The valve 5 thentips off of the seat 4 until its upper rounded surface abuts against therounded lower end of the stopper 7 this locking relation of the valveand stopper giving a maximum clearance for the outpouring of the liquid,while causing the valve or plug 5 to immediately drop back on its seatas soon as the bottle has reached such a position where it might bepossible to cause liquid to leak therein. The zig-zag or tortuousrelation of the ports 13 prevents the insertion of any implement, suchas a Wire by means of which the valve 5 may be manipulated, and theconstruction of the valve of material which is magneticallynon-conductive prevents the lifting of the latter by means of a magnet.Furthermore the space between the valve 5 and the bottom of the stopperis such that together with the rounded surface of the tube, it isimpossible to wedge the valve in any Way so that it cannot fall backupon its seat.

What I claim as my'invention is The combination with a bottle neck, hav-Gopies or this patent may be obtained for ing an annular valve seat inits inner end, of a substantially conical valve engageable on the seatand having a, convex upper surface, a stopper cylinder in the bottleneck loosely confining the valve and having a convex lower face opposingthe convex face of the valve, and means for locking the stopper cylinderin the bottle neck, said cylinder being provided with ports extendinglongitudinally therethrough.

In testimony whereof, I aflix my signature, in the presence of :twowitnesses.
